Definitions

  • the invention relates to a plate-shaped insulating element made of molded plastic for ventilated rafter pitched roofs.
  • Such insulation elements are commercially available as flat panels, which can be assembled on their longitudinal edges by means of multiple tongue and groove profiles and thereby provide a tight butt joint.
  • the formation of the joints is complicated and, as a result, they are prone to failure in practice, and cuts and connections are difficult to produce. Since this tongue and groove profiling can practically not be retrofitted at the installation site, it is necessary to lay the prefabricated, plate-shaped insulation elements with their given standard dimensions. This does not ensure that the butt joints of the insulating elements arranged side by side always run along rafters, which results in tightness and stability problems.
  • counter battens In order to finally allow proper ventilation of the roof covering, counter battens must first be nailed onto the insulation elements above the rafters, which can then accommodate the transverse roof battens for the application of the roof covering.
  • insulating elements for longitudinal rafter pitched roofs which are designed as comparatively narrow slabs to be laid transversely to the rafters with a profiled lower edge such that, after the insulating elements have been laid, a slatted structure for receiving the roof covering results directly in order to apply No need for roof battens on the installed insulation elements.
  • this lath-shaped structure of the insulating element profiling which runs horizontally on the pitched roof, prevents moisture from penetrating the roof coverings. The fact that this penetrating moisture cannot be removed is all the more serious since rear ventilation between the insulation elements and the roof covering is not feasible.
  • the invention has for its object, plate-shaped ge insulation elements of the type mentioned to the extent that they are easily accessible to the roof truss geometry of a rafter pitch roof with properly ventilated roof covering while maintaining simple installation and are equally mechanically stable and, taking into account inevitably reduces the roof covering penetrating moisture, a securely sealing pitched roof Allow material and labor to be realized.
  • a plate-shaped insulating element of the generic type in that it is designed as a foam-integrated profile part with a longitudinal edge in the form of a Z-profile, from the plate surface transversely to its projecting web and a projecting flange connected to the web edge.
  • foam-integrated Z-profile which protrudes above the panel surface, not only replaces the counter battens to ensure proper roof clearance ventilation, but also ensures due to the bending stiffness of such a profile , increased mechanical stability of the insulation element.
  • the overlapping of the non-profiled longitudinal edge of an adjacent insulation element provides a good side joint seal. Since the non-profiled longitudinal border does not require any tongue or groove formation or any other special training for the connection, insulation elements can be supplied in standard widths and can be shortened to a width at the installation location simply by cutting a strip along this un-profiled longitudinal border corresponds to the specified rafter spacing. Since the side joints always run on the rafters, both the sealing and the load-bearing capacity are further promoted.
  • All-e materials that are used for foam insulation elements and are usually based on polyurethane are suitable for the foamed plastic insulation element with the foam-integrated long side profile. Dimensions and thicknesses of the insulation elements can be standardized in any gradation. The insulation elements can be laid on roofs of any inclination with longitudinal rafters.
  • the preformed U-profile is expediently partially foamed into the insulating material plate in such a way that half of it protrudes beyond its longitudinal edge.
  • the interior is filled with foam to such an extent that a gapless connection to an adjacent insulation material plate, which is overlapped by the Z-profile in the edge area, is guaranteed with regard to the yoke dimension of the insulation material plate.
  • a prefabricated U-profile to be foam-integrated with the insulating material plate is expediently selected, one of the legs to be foamed in is formed on its end face with an anchoring profile and the other leg is formed directly as the cutting edge.
  • the water guiding rib formed in one piece with the insulation board can simply be cut off or scraped off, so that despite any simple adaptability to given geometric conditions, the sealing and mechanical securing function of the the side impact overlapping Z-profile in the plate-shaped insulating element according to the invention is in no way impaired.
  • this is a profile part which consists of a essentially flat, foamed plastic insulation material plate 2 and a profiled part in the form of a Z-profile 4 formed along one of its two longitudinal edges 3, 11 and consisting of a foam-integrated part.
  • This Z-profile 4 is composed of a web 6 which extends in the direction of the longitudinal edge 3 and transversely to the plate surface 5 and a vorkra-.g flange 7 which adjoins the upper web edge 8 and above the plate surface 5 parallel to this via the longitudinal edge 3 of the insulating material plate 2 also protrudes.
  • this protruding flange 7 is preferably selected so that its lower flange surface 9 lies in the plane 10 of the plate surface 5. In this way, in the area of this profiled longitudinal edge 3, a tight connection to an adjacent insulating element 1 of the same panel thickness is possible, the non-profiled longitudinal edge 11 of which is overlapped by the projecting flange 7 of the Z-profile 4.
  • a cutting edge 13 running parallel to the web 6 and projecting below the plane 10 of the plate surface 5 is formed on the free end edge 12 of the protruding flange 7 of the Z-profile 4.
  • This serves a line-shaped Eincehneiden in the plate surface 5 of an adjacent insulating element 1 parallel to its unproflilierter longitudinal edge 11. This ensures a self-sealing connection along such side joints 23 (see FIG. 3).
  • water-guiding ribs 14 serve to relieve the side jolts in the area of the Z-profiles in the case of insulating elements 1 arranged next to one another, by preventing a large-area lateral drainage of moisture accumulated on the plate surface 5, in particular in the direction of the non-profiled longitudinal edge 11. Rather, this moisture is locally limited vertically and thus quickly dissipated to the eaves.
  • the Z-profile 4 on the profiled longitudinal edge 3 of the insulating material plate 2 in that a prefabricated, elongated U-profile when creating the insulating material plate 2 with a leg 16 into it Insulating material plate 2 is foamed in that the yoke 17 of the U-profile 15 is arranged above the plane 10 of the plate surface 5 and parallel to it projecting beyond the longitudinal edge 3 and facing the insulating material plate 2 with the U-profile opening.
  • the molded leg 16 is preferably equipped with an anchoring profile 18 at its free end. As taken into account in the drawing, this can be designed as a double-sided rib of triangular cross section, but also as a simple angled portion or as an alternate spread of successive leg sections (not shown in the drawing).
  • the interior 19 of the U-profile is essentially foamed in one piece with the attached insulating material plate 2, preferably in such a way that the longitudinal edge 3 never runs through the elongated U-profile 15 approximately in the plane of the longitudinal center line.
  • a limitation of the foaming in the plane 10 of the plate surface 5 is the lower flange surface 9, over which the cutting edge 13 projects downwards. This is preferably formed in that the second leg 20 of the U-profile 15, which is not foamed into the insulating material plate 2, has a cross-section tapering towards the free end edge.
  • This preformed U-profile 15, which results in the longitudinal edge a-Z profile 4 by foaming in the insulating material plate 2, can consist of a nailable or screwable plastic, or can also be designed as a metal profile. In the latter case, a metal grid profile is preferably used in order to be able to nail or screw through the yoke 17 into the foaming of the interior 19,
  • the plate-shaped insulation element and its particular constructive and application-oriented distributions result from FIG. 3.
  • the plate-shaped, profiled insulation elements 1 are defined next to one another such that the side joints 23 Insulation elements 1 arranged next to one another and each towered over by the Z profile 4 extend on the rafters 22.
  • the insulation elements 1 which are delivered in standard dimensions, on their unprofiled L ijnsberandung 11, by simply sawing off a strip of the Dämmaterialplatte 2, adapted in its width to the center distance between those rafters 22 on which the side ver convinced.sollen shocks 23rd
  • the roof battens 25 running transversely to the rafters 22 are fastened directly to the flanges 7 of the Z-profiles 4 projecting above the panel surface, whereupon the roof covering 24, for example in the form of roof tiles, can be applied.
  • the rear l ü f tung cross-section is so by the upwardly projecting over the plate surface 5 of the web 6 of the high Z-Pro- f iles 4. directly secured without having to use specially material or work.
  • Breakthroughs of the insulation elements 1, z. B. for penetrating a fireplace, or edge connections can be easily made, since the foamed insulation elements 1 can be easily machined with conventional tools. Connections, including butt butt joint joints 26 between insulating elements 1 adjoining one another in the longitudinal direction can be securely sealed without great effort and at the same time mechanically secured, for example by injecting commercially available spray foam based on polyurethane.
  • the insulation elements 1 can therefore also be used reliably in the case of complicated roof trusses, even in the case of large or heavy pitched roofs, because the foam-integrated Z-profile 4 noticeably increases the structural strength of the plate-shaped insulation elements 1 due to its flexural rigidity due to its flexural rigidity .
  • the underside of the plate 27 of the foam-molded insulation elements 1 can be provided directly with coatings, for example with wood coatings, which supports the particular suitability of this plate-shaped insulation element 1 for old building renovation or for subsequent attic expansion.
  • the invention is therefore not limited to the exemplary embodiments and details shown. It also includes all professional modifications and further training as well as partial and sub-combinations of the features and measures described and / or shown.
